Zahn Cup

BGD 126 Zahn Cups can be used to quickly measure the viscosity of liquids such as Paint, Ink, Varnishes, Syrup and Oil. It is produced according with ASTM D 816, ASTM D 1084,ASM D 4212.The Stainless Steel Cups are molded precisely and the orifices are precision drilled using high-speed CNC drilling. Each cup has a 12-inch loop handle to allow the cup to be dipped by hand into a liquid container. At the center of this handle is a finger-ring for holding the cup in a vertical position during use. Its orifice diameters adjusted at the factory for appropriate results with applicable NIST traceable Newtonian oils. It is done by filling up the volume of Zahn Cup with the required liquid, and then used a index finger to stop any flow out of the liquid. A ring at the Zahn Cup handle allows the cup to be hanged perpendicularlystill with the finger stopping any liquid flow out.Prepare a Digital stopwatch and set zero. Immediately start the stopwatch when the finger is released. As soon as there is a first break of the flow, stop the stopwatch. The second shown is the time of the liquid flow, which is also the flow viscosity of that liquid.Main Technical Parameters 1. Volume of Cup44ml 2. Length of Handle40±0.1mm 3. Height of Cup58±0.1mm 4.

Hence, a precision stopwatch is required. Results should be reported in Zahn-Seconds at a specified temperature for a particular cup. To convert Zahn-Seconds to centistokes, refer to ASTM D 4212 Centistokes ×Specific Gravity= Centipoise
